ABSTRACT
Ornithonyssus bursa, known as the "tropical fowl mite," is a hematophagous mite of domestic and wild birds, which occasionally bites humans. Accidental bites on humans occur mainly when abandoned bird nests are close to homes or when people are handling parasitized birds. In the present study, we describe five case reports of bites on humans and new records of localities for this species. Based on the material examined, we provide morphological and molecular characterizations for this species herein.

ABSTRACT
Mites that affect animals (acariasis) can occasionally be transmitted to humans by incidental contact producing pruritus and dermatitis. Animals such as dogs, cats, mice, birds and reptiles, harbour several mite species. Hemophage mites and those that feed on lymph have the potential of transmitting important zoonotic agents (cuales??). The presence of lesions of unclear origin and a history of contact with pets or wild animals should alert towards the possibility of acariasis. Diagnosis is based on direct visualization of the mite,analysis of its morphology and obtaining information on the animal host. Awareness of these acarosis and the responsible care of pets and animals are the most relevant preventive measures.
Los ácaros de animales (acariasis) pueden transmitirse en forma accidental al hombre al estar en contacto con ellos, produciendo lesiones características (pápulas o vesículas) y ocasionando una dermatitis pruriginosa (acarosis). Existen diversas especies de ácaros, que se encuentran en perros, gatos, roedores, aves y reptiles. Los ácaros hematófagos o los que se alimentan de linfa tienen el potencial de transmitir importantes agentes zoonóticos. La presencia de lesiones sin una etiología clara y el antecedente de contacto con animales, tanto mascotas como animales silvestres, ayudan a plantear esta etiología. El diagnóstico se realiza con la visualización del acaro, morfología y tipo de hospedero animal. El conocimiento de estas acarosis y el control responsable de mascotas y animales, son las principales medidas de prevención.
